I most always have a Tahoe as a toad behind me. We had just finished with major repairs in the engine compartment one of the regulators we updated was for the tag axle. We thought we had set the pressure at 35 psi. With the generator, fuel tank and propane tank all riding on the front axle she felt really heavy that day. We blew the front drives steer tire off the rim at 70 mph, they were new tires with less than 5,000 miles. the only thing we could determine for the failure was my tag axle pressure changed to over 65 psi overloading the front axle. The tag axle is there to help stabilize your ride and carry some of the weight of the engine and to help when you may have a heavy trailer tonge weight.
If you don't have accuses to a scale, you can pull measurements on level ground from the frame to the ground to check if your ride height is level. If the tail of your coach is too high, it will cause your toad to ride nose high wearing out the suspension and tires.
I saw another comment about running different air pressures in your tires for a better ride or softer ride. I run 110 psi year-round the air ride system will manage your comfort and stability of the coach. if you run loaded tires to low on-air pressure, they will build heat and fail. In the old days we would adjust air pressures because of the steel coil suspension like in our old Gas Class A's that had the P-30 cassis.
Buy the way it was the Monaco air ride suspension that keep the coach upright after losing the steer tire that day it automatically tries to balance the coach while in turns to prevent the coach from swaying and leaning into turns. We just held her straight down the road until she slowed down enough to pull off the road.
